This is a re-enactment of a scene from a Spanish movie "Intacto". The premise of this movie is that luck is a property which people possess and the property can be transferred from one person to another. So in this case, a bunch of people run blindfolded through a city. The ones who don't get killed by traffic or run into a brick wall are the ones who are lucky. They will move to the next level of competition to find which among the luckier is the luckiest.
In the movie there is a whole 'nother plot with Holocaust survivors and casinos and people being able to steal other people's luck.
I have to say, for some reason this idea really appeals to me because despite my totally rational outlook on life, deep inside I have this superstitious belief that luck exists.
